Final heat treatment of gear

Considering that there are certain differences in the carbon concentration and distribution uniformity on the gear surface, such differences in carbon elements make the gear easy to change its expansion coefficient in the final heat treatment stage, resulting in gear deformation. From the actual situation, in the process of gear processing, if there is no necessary monitoring operation on the carbon potential and the process flow, it is bound to lead to different carbon concentrations on the surface of gear parts in each furnace, and the permeability of carbon elements will also be different, and the difference will be large, which will directly lead to the gear deformation in the process of heat treatment in a disordered state. Based on this understanding, technicians need to effectively control the carbon element during the final heat treatment, so as to keep the carbon concentration and penetration depth on the surface of gear parts within a reasonable range. In this process, technicians need to use more advanced carbon automatic control technology, with the help of modern technical means, to carry out necessary control on carbon concentration and carbon penetration in the boiler, and from the technical level, to ensure the rationality of carbon element distribution on the gear surface and inside. In addition to adopting modern carbon automatic control technology, Technicians need to install heating devices and necessary cooling equipment. In this way, the temperature can be controlled within a reasonable range, so that the relevant equipment is always in a good operating state.
